And as for only suggesting male guppies, there is a chance of a little fighting, but from my experience, guppies are pretty docile. And even with "nature taking care of itself" if you have places for the fry to hide, then some will probably live and I just figured since you were getting back in the hobby that you wouldn't want to worry about overstocking because of the fry living or something, that's all. Personally, I just thought having to worry about babies when you are just starting the tank isn't the best route to go, but if you want fry, then by all means, have both males and females. But from my past experience, male guppies are a fish species that you can just keep males of, I had 6 males in a 10 gallon with some silk plants and had no problems, I just didn't want to worry about fry because I hate rehoming fish, and couldn't deal with constantly trying to rehome them because I am too picky. But that's just me though, I am too attached to my fish, even fry lol. So I am sorry if you took offense to that.
